A chemist has a 9% acid solution and a 4% acid solution. He wishes to make 3 liters of a 7% acid solution. ANSWERS ASAP!
There are four parts to it:
A)There's a chart with 3 sections labeled "liters of solution", "percent acid", and "liters of acid".*
B)Write an equation to find how many liters of each solution the chemist must mix together to make 3 liters of a 7% acid solution.
C)Solve your equation.
D)How many liters of each solution must the chemist mix together?
*Three rows going down say "9% acid solution", "4% acid solution", and "7% acid solution".
